United States Patent 3,420,246 METHOD FOR CURLING HAIR Sterling O. Stageberg, 18210 Sunset Blvd., Redington Shores, Fla. No Drawing. Filed Apr. 26, 1965, Ser. No. 451,013 US. Cl. 132-7 5 Claims Int. Cl. A4541 7/00 ABSTRACT OF THE DISCLOSURE Hair is curled by encasing each strand of hair in a water repellent material, then placing the hair strands between complementary pressure applying members, one of which is formed of resilient material and the other of which comprises a nonyielding blade edge curved on a radius of about .010 inch, forcing the blade against hair strands by bending thereof to drive the edge of the blade and the segments of the hairs engaged thereby to a depth in the resilient member of the order of .015 inch to bend, stretch and distort the hair beyond its re covery point.

The present invention relates to a method of curling hair and is an improvement in the method of curling hair disclosed and claimed in my United States Patent No. 2,808,838.

It is well known that when a persons artificially curled hair is subjected to moisture it tends to return to a straight condition and the curl is destroyed. This is particularly true of a water induced pin curl and is true to a lesser extent with hair curled by the method of the aforementioned patent.

The principal object of the present invention is the provision of a method of curling hair which results in curls which are unaifected by moisture of any degree so that even complete immersion of the hair in water will not cause a lessening of curling tendency.

In carrying out the invention, the method comprises first waterproofing the hair by a suitable material which may be applied by dipping the hair in liquid waterproofing material, after which the hair is curled in the manner set forth in the aforementioned patent, that is, placing the hair between two members one of which is a bladelike element having an edge which is pressed to hair which is between the two members so that the hair is bent by the blade-like member under a pressure of 1,000 p.s.i. and in which bending pressure is repeatedly applied along the length of the hair in segments of hair in the order of .030 inch to .050 inch in length.

In carrying out the invention, the hair is first washed and then thoroughly dried after which it is immersed in a suitable liquid waterproofing material to coat each hair therewith. The waterproofing material may be a wax and water emulsion which when dried forms a waterproof coating over each hair, or the waterproofing material may be of a penetrating type which penetrates the hair and deposits water repellent material therein. The latter waterproofing agent may be of the so-called silicone ty e. Suitable waterproofing materials are readily available on the market and are well known, and ordinarily are used in treating cloth and the like to render the same water repellent.

After the hair has been treated with waterproofing material as described, it is dried by heated air passed through the hair, the air temperature being as high as can be accepted by the person. Following the drying step the hair is then subjected to bending and stressing to Ice provide curling thereof as set forth in the aforementioned patent so as to produce curls therein. By forming the curls after the hair has been waterproofed, the hair is impervious to moisture and therefore it will retain its form regardless of the amount of moisture which may come into contact with the hair.

Furthermore, I have found that treating hair as described herein has a therapeutic value and the hair of the curls is glossy rather than dull, and the treatment imparts a lively, healthy appearance to the hair. The water repellent on the individual hairs sheds any water to which the hair is subjected whether from swimming, bathing, etc. and the curls remain unaffected.

Although I have described but one form of the invention, it is to be understood that other forms, modifications, and adaptations could be made all falling within the scope of the claims which follow.

I claim:

1. A method of curling hair which comprises coating individual hairs with a water repellent material in liquid form, substantially drying said material on the hairs and then curling the hair by subjecting each hair to a bending pressure in the order of 1,000 p.s.i., the bending pressure being repeated along the length of each hair and the application of pressure being confined to a portion of a length of the hair in the order of .030 inch to .050 inch at each application of the pressure.

2. A method of curling hair which comprises drying the hair, coating the hair with a waterproofing agent comprising a wax emulsion in water, substantially drying said material on said hair, and then curling the hair by subjecting each hair to a bending pressure in the order of 1,000 p.s.i., the bending pressure being repeated along a length of each hair and the application of pressure being confined to a portion of the length of the hair in the order of .030 inch to .050 inch at each application of the pressure.

3. A method of curling hair which comprises coating the hair with a waterproofing agent in liquid form comprising a silicone, substantially drying said agent on the hair, and then curling the hair by subjecting each hair to a bending pressure in the order of 1,000 psi, the bending pressure being repeated along a length of each hair and the application of pressure being confined to a portion of the length of the hair in the order of .030 inch to .050 inch at each application of the pressure.

4. A method of curling hair which comprises washing the hair, drying the hair, coating each hair with a waterproofing agent in liquid form, substantially drying the coated hair, and then curling the hair by subjecting each hair to a bending pressure in the order of 1,000 p.s.i., the bending pressure being repeated along a length of each hair and the application of pressure being confined to a portion of the length of the hair in the order of .030 inch to .050 inch at each application of the pressure.

5. A method of curling hair which comprises coating the hair with a waterproofing agent in liquid form, substantially drying the coated hair, and then positioning the strands of hair between complementary pressure applying members, one of which is formed of resilient material, and the other of which is in the form of a nonyielding blade, an edge of which is convexly curved on a radius of approximately .010 inch, with the hair extending crosswise of said edge of said blade; bringing said pressure applying members together with a force sufiicient to drive the edge of the blade into the resilient member to a depth on the order of .015 inch to thereby apply mechanical pressure laterally on a minute por- 3 4 tion of the hair, on the order of .030 inch to .050 inch References Cited long, which pressure is sufiicient to bend, stretch and dis- UNITED STATES PATENTS tort the hair beyond its recovery point; and repeating said pressure application while effecting relative movement between the hair and the complementary pressure 5 applying members lengthwise of the hair so that the deformations of the hair thus produced occur at close LOUIS MANCENE Examme" intervals along the length of the hair.
